#..  C Compiler definition
#   Notes:
#   The Keil compiler has a specific ordering of files on the command line
#   The standard definitions are bent to fit
#
#   The compiler does not support specification of include directories
#   on the command line. They are done via the C51INC environment variable
#
#   The compiler defines __C51__
#
#   The shell used by make needs the XX() constructs to be esacped
#
#   The compiler does not take include files on the command line
#   These MUST be passed via the environment variable C51INC
#
#   Convert user CFLAGS from -Dxxxx -> DF(xxxx)
#
#   The command line is VERY limited
#   Use abbreviations at all times
#
